The results showed that there were significant differences among fungal species or ecotypes in all above index,which varied with soil types.First,six fungi could colonize maize root on three soils,and the fungal colonization rate was higher on soil collected in the region that had been screened for cinnamon soil and brown soil.

结果表明，6种菌株在上述指标上存在显著的种间或生态型差异，土壤与菌株间存在显著的交互作用。6种菌株在3种土壤上都能与玉米形成菌根，在褐土和棕壤上大多数菌株在分离地所在地区土壤类型上的菌根侵染率较高，说明其对该土壤条件的适应性较强；在红壤强酸性土壤条件抑制了菌根真菌的侵染。

The inoculation effectiveness of fungi varied with soil types,especially for BEG167.BEG167 performed positively on cinnamon soil,and neutral on brown soil,but negatively on red soil.Except for BEG150 all All other fungi,except BEG150,increased maize P uptake on cinnamon soil and brown soil,however,only BEG168 and BEG 141 improved P uptake significantly on acidic soil.

若以真菌的根外菌物量作为衡量AM真菌菌株土壤生态适应性的指标，BEG141和BEG167是生态适应性强的菌株，为广幅生态型菌株；菌株BEG168和BEG151次之，前者在棕壤上适应性高，后者在红壤上适应性高。

Totally two strains of O serotype FMDV invasion occurred in Taiwan since 1997. The first invasion of FMDV occurred in March, 1997. It belongs to porcinophilic FMDV (O/Taiwan/97), the virus won't infect cloven-hoofed animals except pigs.

台湾从1997年以来有两株O血清型口蹄疫病毒株入侵，第一次在1997年3月，由亲猪型的口蹄疫病毒株(O/Taiwan/97)所引起，这株病毒不会感染猪以外的偶蹄类动物。

检测102株大肠埃希菌中，仪器检出41株阳性，纸片协同法对照也为阳性，但仪器检测的61株阴性菌中，纸片协同法对照有19株为阳性。

Objective To investigate extended-spectrumβ-lactamasesand AmpCβ-lactamases and metalloβ-lactamasesproducing by gram-negative bacilli in burns.Mehtods Adopitng double-disk synergy test,modified three-dimensional extract test and the enzyme inhibitor of EDTA-Na2to detect ESBLs and AmpC and mBLA producing strains.Using K-B test to perform the susceptibility testing.Results Among348strains of gram negative bacilli,ESBLs,AmpCβ-lactamases,ESBLs combined with ApmCβ-lactamases and mBLA produc-ing strains were found in122,47,9and20strains,the incidence being35.1%,13.5%,2.6%and5.7%respec-tively.

目的 了解烧伤感染主要革兰阴性杆菌产超广谱β-内酰胺酶、AmpC酶和金属β-内酰胺酶及其对常用抗生素耐药性情况，指导烧伤医院感染合理用药方法采用双纸片协同试验检测产ESBLs株，头孢西丁三维试验检测产AmpC酶株，头孢曲松三维试验检测同时产ESBLs和AmpC酶株，依地酸二钠协同试验检测产mBLA株，K-B法进行G -杆菌药敏试验。

Main microorganisms of chilled mutton made in Tacheng area were incubated with selective agars.

采用选择性培养基从新疆塔城区冷却羊肉中分离和初步鉴定出乳杆菌2株、热死环丝菌2株、假单胞菌属和肠杆菌科各3株，葡萄球菌属和酵母菌各1株。

Results It was found that the types and quantities of metablic organic acid of all anaerobes but two strains of lactobacillus were coincident with the standard of identification of anaerobes,and the total coincidence was 97.67%.

结果 60株细菌中，有48株细菌测到所有代谢有机酸，10株细菌测到主要代谢有机酸，2株细菌测到不应有的代谢有机酸，总符合率为97.67%。

The primers and the detection programs have been used to detect the pathogens in the inoculated-diseased cucumber plants .The details are reported as follows: 1. By using the primers ITS1/ITS4, only Fusarium isolates could be amplified to produce a special fragment of 750bp. This product generated 480bp, 200bp and 100bp fragments after digested by restriction enzyme HinfⅠonly from the pathogen of Cucurbits Fusarium Wilt.

引物ITS1/ITS4只在镰孢属菌株上扩增到一条750bp分子片段，其他供试菌株无扩增条带产生，扩增产物经HinfⅠ酶解后，只有瓜类尖镰孢菌产生480bp、200bp和100bp 3条带，说明该PCR-RFLP程序对瓜类尖镰孢菌具有特异性；巢式PCR引物BIK1/BIK4和BIK2/BIK3只有在黄瓜尖镰孢菌菌株上扩增到一条800bp分子片段，其他菌株均无扩增条带产生，说明该巢式PCR程序对黄瓜尖镰孢菌具有特异性。

In the presence of ADR, H+ effluxes in MCF-7/R cells were nearly 5 times more than that in MCF-7/S cells.
